In the figure, if AB || CD, then angle EFD is equal to:(a) 50(d) 40(c) 20(d) 30
2 answers:
Answer:
d. 40°
Step-by-step explanation:
70-30=40°
Answer:
d) 40
Step-by-step explanation:
AB || CD, so ∠DCB + ∠ABC = 180 { co interior angles }
∠DCB + 70 = 180
∠DCB = 180 -70 = 110
∠FCE = ∠DCB { Vertically opposite angles }
∠FCE = 110
In triangle CFE
∠EFD + ∠CEF + ∠FCE = 180 ( sum of angles of triangle)
∠EFD + 30 + 110 = 180
∠EFD + 140 = 180
∠EFD = 180 -140
∠EFD = 40

Answer:
y=-1/3x+4/3
Step-by-step explanation:
y-y1=m(x-x1) m=1/3 x1=3 y1=2
y-2=1/3(x-2)
y-2=-1/3x-2/3
y=-1/3x+4/3
